Calix[4]arene–carbazole-containing polymers: Synthesis and properties

Fluorescent linear polyurea based on toluene diisocyanate: Easy preparation, broad emission and potential applications

“…Nowadays a huge amount of studies are being reported for various applications [2][3][4][5][6][7][8][9][10]. It is to note that, just about two decades ago, a prerequisite to be fluorescent for any organic substances including polymers was that their molecules contain at least one chromophore group, such as cyanine [11], triarylamine [12], pyrazoline [13], carbazole [14], benzoxazole [15], benzothiazole azo [16,17]. The common feature for these materials is that they all contain aromatic building blocks or conjugated structures acting as emitting entities [4][5][6].…”

Die Zippammer – mediterraner Charaktervogel in steilen Weinbergslagen

“…CALIX‐PPE‐3,6‐CBZ,29 CALIX‐PPE‐2,7‐CBZ,29 and CALIX‐ p ‐PPE30 were synthesized according to our reported methods. The number‐average molecular weights and degrees of polymerization of the polymer batches used in this study were of similar magnitude to those presented in the original reports, as estimated by 1 H NMR spectroscopic end‐group analysis.…”

“…We recently synthesized phenylene‐ alt ‐ethynylene‐3,6‐ and 2,7‐carbazolylene polymers that contained calix[4]arene units (Scheme ) 29. These prototype molecular receptor based conjugated polymers (CPs) were designed for the fluorescence sensing of a wide range of analytes, in particular, explosive materials.…”

Excellent performance of aromatic polyguanamines induced by multiple hydrogen bondable tetraazacalix[2]arene[2]-triazine ring in their main chain

“…11,12 Conjugated polymers are one of the hot research topics both in academic and industry, and calix [4]arenes were incorporated as a pendant side group, which enhanced the polymer solubility and was utilized as sensors toward various classes of molecules. [13][14][15][16][17][18][19] On the other hands, calixarenes are known to have a rigid structure, making their incorporation into a polymer backbone relatively difficult unless exible solubilizing groups are introduced at the same time. Dondoni et al synthesized a bisphenol A-type polymer having a calix [4]arene moiety in its main chain and studied Ag ion recognition.…”
